What it means
The S-366 sign is placed over the carriageway on a motorway or dual carriageway to indicate an immediate exit toward a conventional road and the route continuing straight ahead. It allows you to distinguish the lane or slip road exiting toward the conventional road from the route that continues on the main road. It usually appears at links where the decision must be made by lanes and with sufficient visual anticipation. When you see it, read the panel for your lane, confirm your destination, and do not change path abruptly. In the test they often check that you combine immediate exit, high-capacity road, and continuation of the main direction.
